1. A medical apparatus comprising:

  • a magnetic resonance imaging system for acquiring magnetic resonance data;

    a processor for controlling the medical apparatus; and

    a memory containing machine readable instructions for execution by the processor, wherein execution of the instructions causes the processor to;

    acquire a first set of magnetic resonance data;

    reconstruct a first image using the first set of magnetic resonance data;

    acquire an undersampled magnetic resonance data set, wherein the undersampled magnetic resonance data set is undersampled in k-space in comparison to the first set of magnetic resonance data;

    reconstruct a second image using the undersampled magnetic resonance data set and the first image, wherein the second image is reconstructed using an image ratio constrained reconstruction algorithm; and

    calculate a temperature map using the second image.
